Streptomyces adverse health effects

Can anyone clue me in to known potential adverse health effects from
Streptomyces inhalation exposure? In an office where Streptomyces is
present people are reporting headaches and some upper respiratory
effects. It is not known yet whether other microorganisms are present.
